Is Grapeseed Oil Acidic or Alkaline?
Grapeseed oil (raw) is neutral: PRAL close to zero: hardly shifts your acid-base balance.
Classification
Grapeseed oil is at 0.0 and neutral because it is pure fat with no protein, phosphorus or minerals. The fact that grapes themselves are alkaline at −3.8 doesn't help here, because everything mineral stays behind in the seed during pressing. So in a dressing the oil is neutral, and the vinegar, mustard and salad greens decide the balance.
In the Oils & Fats category, grapeseed oil (raw) ranks #17 of 22, sorted from alkaline to acid-forming. More alkaline options include Walnut oil (0.0), Soybean oil (0.0), Almond oil (0.0). More acid-forming are Olive oil (0.0), Lard (+0.1), Clarified butter (+0.1).
Acidic or alkaline: PRAL, not pH
On this site, acidic and alkaline refer to the PRAL (potential renal acid load). It estimates what a food leaves behind once it has been digested: a positive value is acid-forming, a negative value is alkalizing. That is different from the pH of the food itself: a lemon tastes sour, yet its PRAL is −4.0, so it is alkalizing. Your diet does not change your blood pH. It does change how much acid your kidneys have to deal with.

Frequently Asked Questions
Is grapeseed oil acidic?
It depends on what you mean by acidic. The pH describes the food itself, for example how sour it tastes. The PRAL describes what it leaves behind after digestion: Grapeseed oil (raw) has a PRAL of 0.0 per 100 ml, so it counts as neutral in your daily acid-base balance.
Does grapeseed oil count in the acid-base balance at all?
Hardly. At 0.0 per 100 ml, grapeseed oil is in the neutral range between −0.5 and +0.5. You can eat it without shifting your balance.
